=head1 RECIPES

=head2 UTF8 data

When you're using UTF8 data, you may run into the "Wide character in print"
warning. To fix that in 5.8+, do the following:

  my $db = DBM::Deep->new( ... );
  binmode $db->_fh, ":utf8";

In 5.6, you will have to do the following:

  my $db = DBM::Deep->new( ... );
  $db->set_filter( 'store_value' => sub { pack "U0C*", unpack "C*", $_[0] } );
  $db->set_filter( 'retrieve_value' => sub { pack "C*", unpack "U0C*", $_[0] } );

In a future version, you will be able to specify C<utf8 =E<gt> 1> and
L<DBM::Deep/> will do these things for you.
